Module 2: Lahars
The first GIS application investigated in GIS 4048 is Natural Hazard planning and mitigation. For the lahars lab, students utilized DEMs and the Hydrology toolset found within the Spatial Analyst extension to determine potential drainage flow around Mt.Hood in a potential volcanic event. After streambeds were determined, students overlaid census data to determine the at risk population. Lastly, the data was compiled as a cartographically polished map to effectively communicate the information.
